Hey all. This blog records my thoughts of the day about my life on the Eclipse CDT project. I will occasionally give opinions and news regarding the Eclipse CDT - the project and its ecosystem - and on open source in general. Please feel free to comment on anything I say. I appreciate it when people are honest with me. And, please, please, consider all of these opinions mine, not of my employer.
Just for fun (and maybe profit), I thought I'd try and get Qt running on the mini ARM Linux setup that I used for my tutorial at EclipseCon. Low and behold, all I had to do was build it with the compiler I got from CodeSourcery for ARM and it worked!
Now there isn't a whole lot of magic here. It's using the Linux framebuffer device that draws to the screen. I'm not sure how it would look on a real device but it looked might fine on qemu. Here's a snapshot of it running on my laptop, which is now solidly Fedora. It's running the browser demo app and has loaded my blog just before I posted this. It took a little while to load and render, but again, it looked pretty good.
Having gotten this far, I start to wonder how much better it would be if I had OpenGL ES emulation in qemu. Would it be faster? Curiosity might kill this cat...
An update to my previous post. As proof I got it working, here's my blog from earlier today. You can't see the flash since apparently the adobe flash player bypasses the widget set and opens a native window directly. Wonder where it showed up... At any rate, lots of fun. And with OpenGL mode turned on, performs quite nicely and the widgets are quite readable. Click on the picture to see full size. Very nice.
As the shiny balls spin around in my world, Qt has jumped back into the foreground. My Fedora laptop is busy building 4.5 as I write this and slowly catching on fire (man these things get hot when they're busy working). While that was going on, I took another look at how you'd implement Qt widgets in 3D space, kind of like Clutter does in a GTK fashion (mind you I think those are just static 2D images, not widgets).
Low and behold, I came across the Qt Lab Blog entry by someone there who actually has a demo of Qt widgets running in a maze similar to the old id games. He called it WolfenQt. Take a look here:
Very cool! This is exactly how I was hoping it would look and feel. And Qt has the framework to make it happen. I need to do some experimentation with it once I my 4.5 compiled to see how much of this is done in OpenGL versus software rendering. Looking at the code it looks like quite a mix of both. But from the video, it looks fast enough. And I do know the marching guy is rendered using OpenGL at least.
This is the kind of innovation I'd love to see. We talk a lot in the Eclipse world about Java thick clients and Browser/Server architectures. But there's still so much more you can do using native APIs that take advantage of all the new hardware acceleration capabilities that today's platform providers are giving us.
And the CDT is such a natural IDE for this new world. With all these new platforms, developers really need a cross platform cross target development environment to work with them all. The goal for my CDT work right now is to show that off and put together IDE packages, like Wascana and maybe something with DSDP for embedded, that can be used in these environments.
